The procedure to reprogram a used KOMBI is
1. Use R270 to clear up the mileage (which is the purpose for R270) Ok
2. Modify the VIN bytes from the binary. Write the modified binary back to the EEPROM Ok but waiting for the information about secondary vin address
3. After doing the above steps, the CPU will treat itself as a brand new one.
Then, you connect the KOMBI to your car,
upgrade the program by using WINKFP Is this for Exx only or also is ok for Fxx, in this case where is WINKFP stored and how to use it
, write VIN by using Tool32 How to do this? i´m new with Tool32
and code it by using E-SYS Ok i know do this

I hope you can understand what i'm talking about. Enjoy!

I´m afraid about version of the this Speedometer, i don´t want to lose Entertainment list and Telephone contacts on HUD because Version less than 47.5

The VIN is showed as 00 but i'm not sure if it's correct. To me, a empty VIN should be all FF. Maybe you emptied them in a wrong way...

If you have already written FF, you may consider recording the new VIN by using Tool32. Go to Tool32, load KOMBI??.prg (i've uploaded komb01.prg coming with the ecu folder of F10 data files), then, you will see the command as c_fg_xxxx. First, try c_fg_lesen to see if you can read the VIN out. It should be showed as all FF. Then, use the command c_fg_schreiben to write the VIN back. Note that you need to input a 18 bit VIN which means an additional checksum bit after the normal 17bit VIN.
